TO ALL wnon IT MAY oonennm 'Beit known that I, 'Jncon CLICK, of Springfield, in the county of Clark, and State of Ohio, have invented a new and useful Improvement in E'arth-Pulverizers or Barrow; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference being lied to the accompanying drawings, in which Figure 1 is a plan view of my invention. Figure 2 is a'sidc elevation of the same.

That others may understand the construction and operation of my invention, I will particularly describe it.-

A A are the transverse timbers forming the frame. These-timbers are securely fastened by'bolts or otherwise to the longitudinal timbers B B, to the front ends of which are attached the draught-hooks C O, to which the team is attached to draw the apparatus. To each of thetransverse timbers A are secured thc'curvod tooth D D, which cut and pulverize the earth as the implement is drawn forward. These teeth are curved backward, asshown in fig. 2, and the forward or convex, edge is sharpened, so that the soil is not merely dragged and dis turbed'but is cut and severed, and therefore it is disturbed to a much greater depth than'would be the case were the teeth blunt. At the upper end of each tooth a shoulder and tang are forged, and the latter is passed through a hole in the transverse timber A A and there secured by scron'muts. It is frequently desirable to disturb the soil to a much greater depth than is ordinarily required. I therefore provide the long teeth E, which are in form and construction like the teeth D, only theyare of .grenter length, as shown. Those teeth are attached to the shaft F, which may be rotated upon its axis in proper bcarings to a certain extent,--suflicient to move the teeth E. from a position nearly horizontal to a position nearly vertical, as shown by black and Ind lines in fig. 2. The levers G G, and connecting-bar H, project from the sideof the shaft F, and by them the attendant is enabled to rotate' the shaft F when desired, but as it would be difficult for himto'retain it in. the desired position by his unaided strength, I therefore provide the ratehetsl I upon the front en'ds of the timbers B B, 'whinh, for convenience and the production of the best result, are curved upward. The penis '.I J are pivoted to the lovers G- G,-and as thesaid levers are drawn backward the pawls engage with the teeth of the ratchet and prevent'a return. of the levers fcrward until such time as the attendant chooses. When it is desired to release the lovers G and permit the teeth E to swing backward again, the attendant draws the cross-bar H backward, and with it the levers G G, until the pawls J J are relieved from pressure, when they maybe simultaneously raised from the ratchet by means of the'handle K, which is attached to the connecting-bar L, and extends thence backward beneath the sross bar H and tom point convenient to the hand of the attendant. The seat M is mounted upon the spring-bars N, and extends entirely across the frame, so that the driver may shift his position as he may desire, and the cross-bar H being of nearly'or about-the same length, the driver may operate the levers G wherever'hc may be sitting upon the seat-M. The intervals between the transverse timbersA A areto be filled with boards, so that the upper surface of the machine presents the appearance of a platform, upon which ballast may beluid ,to increase-the penetration of the cutting teeth. The teeth D D 'are arranged so that the teeth of each succeedingrow will strihe'between the lines of the preceding rows. The adjustable wheels 0 O and P may be used, if desirable, to limit or regulate the depth to which the teeth 1) shall penetrate the ground. They are mounted upon slotted slides which move in guides, and are retained in any position by set-screws which pass through said slots. The wheel is also aJ-caster-wheel, to enable the machine to be turned readily while moving. The wheels 0 O P servo also for the transportation of the machine to and from the field.

Having describerl my invention, what I claim as new, and desire to secure by Letters Patent, -is-- I 1. Constructing a harrow'with a series of long, curved, and sharp-edged teeth or knives, secured to a rotating shaft, so' that they may be depressed .to cut deeply into the ground when desire l, 'substantially as and for the purpose set forth. 4

2. A barrow, constructed with the curved sharp-edged teeth D D and a series of long Info-shaped teeth, E, secured to the rotating shaft F provided with the levers G G, by which said knives E maybe depressed to cut deeply into the ground when desired, substantially as set forth.

3. In combination with the shaft F and levers, G G, the pawls J J and ratchets' I I, substantially as and for.

the purpose'set forth.

4, In combir ationyth the barrow A, and the long seat M mounted thereon, thelevers G G, joined at their upper ends by the long connectingn'od N, as and for the purpose set forth.

5. In combination with their-arrow A, the adjustable wheels 0 O P, for the purpose of limiting the depth to which the-teeth or knives may cut.
